This apparatus relates more specifically to an a paratus for compacting by vibration,

y plastic masses utilized in the construction of roadways and the like.

5 A main object of the invention is to provide a portable apparatus provided with vibratory members capable of compacting plastic material as it is poured in the construction of roadways, ioors, and similar surfaces, and

m which may be readily adapted to compact plastic masses in the Construction of the walls of buildings, dams, and like structures in an economical and effective manner.

Another object is to provide an apparatus x5 that will eectively compact concrete as the same is poured in the formation of roadways and eliminate all air cavities formed therein before the mass is set.

Other objects and advantages will be 4ap- 20 parent from the following description, reference being had to the accompanying drawings which illustrate a single embodiment ofthe invention, in which: l

' Fig. l is a top plan view of a street or roadway during course of construction showing the improved impacting apparatus in use for compacting the material employed in paving the streets; y s

Fig. 2 is a horizontal sectional View through the roadway taken. substantially on line 2-2 of Fig. l;

Fig. 3 is a longitudinal sectional view taken through the preferred f orm of compacting or Vibrating member;

a modified form of compacting member;

Fig. 5 is a sectional view taken on line 5--5 is a section taken on line 8 8 of Fig. e is a horizontal section taken through member is actuated electrically, and especially adapted for the compaction of concrete in the formation of concrete building walls, and the like structures'. In this application the forces created by the vibration of the vibratory members are especially adapted for kthe compacting of lastic masses in the forcast metal having a hemispherical end 12,

and threaded as indicated at 14 to receive a plug 16 to which is attached the vibrating member 18. f A

Vibrating member 18 consists of a head 0r hammer 19' having a shank 22 to which is connectedy a flexible hose 23 which in turn is connected to a shank 24 projecting inwardly from the plug, the hammer having a port or passage 25 extending therethrough adapted to discharge a jet or stream of iiuid against the wall of the casing to effect Vibration.

Vibration of the compacting member is effected by fluid pressure, i. e. by a current of compressed air, or liquid induced through ythe fiexible hose and port in the head whibh forms a jet or stream of Afluid re-acting against the inner surface ofthe casing resulting in rapid vibration or hammering action thereon which in turn is transmitted to concrete in which the impacting member is adapted to be embedded.

An example of the use of the impacting member is shown in Figs. I and 2 in which instance it is illustrated employed in connection with road paving construction. The

impacting member is adapted to be covered y with or embedded in the concrete designated at C and slowly moved along during paving of the street, and at the same time impacting the concrete, a plurality of impacting members being usually employed, dependingon the width of the street, and are connected by cables or chains 26 to a structure the pumpfbeing conveyed to the impacting members through `pipe lines and flexible conduits 31 which are connected thereto by suitable fittings 32 formed on the plugs 16, fluid discharged from the vibrating member being returned to the pump through conduits l 34 and pi e lines 36.

In operation fluid issuing from the nozzlev From t e construction ,itwill be seen that the current of fluid created by the vpump will effect movement of the vibratory member, it being understood, however, that compressed air may be employed in place of fluid.

A modified form of compacting member is shown in Figs. 4 to 8 and consists of a housing in which is mounted a mechanism generally designated at 42 adapted to impart vibration to the housing. A pair of arms 44 and 45 having hammer heads 46 are pivotally connected by pins 47 to a bracket 48 carried by a plate 50 formedintegral with a plug 51 closing the end 52 of the housing.

Movement of the vibrating member is effected by the re-action of a stream or jet o f fluid issuing from a nozzle 54 upon the interior walls of the housing, the nozzle projecting from a sleeve 55 rotatably mounted on a member 56 formed on the end of the arm 45 as shown in Figs. 7 and 8.

Fluid is introduced into the nozzle through a port 58 which communicates with a recess 60 formed in the member, a flexible hose 62 being connected to shanks 63 projecting from the member and plug. The nozzle and arms assume the position shown in Fig. 4 (when at rest) by the action or retractile coil springs 64 and 6 5 respectively, the spring 64 Abeing connected to a pin 66 projecting from a bracket 67 rigid with the plate and a pin 68 on the arm 44, the spring being connected to the pin 68 and a pin 70 extending upwardly from the nozzle.

will cause the arms to swing on the centers of thepins. 47 due to the angular position of the nozzle which is maintained by the spring 65. Immediately after the arms have passed .dead center the spring 64 will aid in moving" the arms. As the arms approach the posif tion shown in dotted lines (see Fig. 4) a tap- )et 72 formed on the nozzle will engage a pin"4 5 which will tend to reverse its position, the movement of which is completed by the spring 65 thereby directing the jet of fluid against the opposite side of the casing wall, the tappet engaging a pin 76 on return movement which serves the same purpose as the pin 75.

' From the foregoing it will be seen that the hammer head alternately strikes the opposite sides of the housing wall, thereby imparting vibratory movement to the impactmg member.

claim: I

1. An apparatus for compacting plastic masses comprisin a casing, a hose connected to one end of sai casing, a head formed of metal having a port or passage extending therethrough connected to said hose, andv means for inducing a circulation of fluid through said hose and the passage throu h said head, whereby there-action of fluid d1scharging therefrom against the side wall of said casing will impart vibrator movement to said head which throu h stri lg on the side wall of said casing wi impart vibration thereto.

2. A compacting apparatus comprisin in combination a casing adapted to be embe ded 1n plastic masses, a vibratory member in said casing, a movable structure, means connecting said casin to said movable structureto move said casmg with it as the concrete is poured, means for developing fluid'pressure carried by said. movable structure, and conduits connecting said casing with said means for developing fluid pressure, whereby'a circulation of fluid will impart movement to said vibratory member.

3. An apparatus for compacting plastic masses comprising in combination a casing, a vibratory member vin said casing comprising a head formed of metal having a port formed therein and a flexible hose connected to said head and casing, a structure adapted to be moved over a horizontal surface, means connecting said casing to said structure, a fluid pressure apparatus carried by said structure, conduits connecting said fluid pressure apparatus with said casing, whereby a circulation of fluid induced by said fluid pressure apparatus through said conduits, vflexible hose and port in said head will impart .vibratory movement to said head by re-action of fluid dischargin from the port therein against the wall o said casing.

4. An apparatus for compacting plastic masses comprising a shell, an oscillatory member mounted within said shell, and means for developin fluid pressure operatively con` nected to sai voscillatory member for oscillating the same, whereby movement of the oscillatory member will vibrate to said shell.
